Abnormal Uterine Bleeding Menstrual Cycle

Abnormal Uterine Bleeding (AUB) • Oligomenorrhea - Interval > 35 days • Polymenorrhea - Interval < 21 days • Menorrhagia regular normal intervals, excessive flow > 80 cc blood • Metrorrhagia irregular intervals, excessive flow and duration • Woolcock JG, Critchley HO, Munro MG, Broder MS, Fraser IS.

Abnormal Uterine Bleeding • AUB is defined as bleeding from the uterine corpus that is abnormal in volume, regularity, and/or timing • Present for the majority in the past 6 months. • Major reason for gynecological procedures • Accounts for 2/3 of all hysterectomies • Kotdawala P, Kotdawala S, Nagar N. Evaluation of endometrium in peri-menopausal abnormal uterine bleeding

Abnormal Uterine Bleeding Treatment Options: • 38 % of women < 40 years of age have unsupported pathology a the time of hysterectomy that are performed for AUB , uterine fibroids, endometriosis or pelvic pain • Recommendations: Medical therapy should be offered if appropriate prior to surgical intervention

Abnormal Uterine Bleeding Von Willebrand Disease • Inherited deficiency or dysfunction of von Willebrand factor • Defective platelet adhesions, slightly decreased VIII activity • Mild or moderate bleeding tendency in in most type 1 and type II patients • Diagnosis: von Will brand antigen, factor VIII, ristocetin cofactor activity , platelet function analysis • Treatment: DDAVP (Type 1) Intermediate purity factor VII concentrate (types II, III)

Abnormal Uterine Bleeding Endometrial Causes • Disorder of the endometrium – Predictable and cyclic menstrual bleeding – Ovulatory cycles – No other causes defined • Deficiencies in local production of vasoconstrictors - endothelin -1 and prostaglandin F 2 alpha • Accelerated lysis of endometrial clot secondary to excessive production of plasminogen activator Increased production of prostaglandin E 2 and prostacyclin which increase vasodilation • • Infection/endometrial inflammation – not well defined

Abnormal Uterine Bleeding • Evaluation of the endometrium – TVUS – Endometrial sampling –Hysteroscopy – Cultures as needed • Evaluation of the endometrial cavity – TVUS 100% sensitive for polyps – Office hysteroscopy • Myometrial evaluation – TVUS and transabdominal ultrasound – Determine relationship of myoma to the cavity and myometrium – MRI – not practical as a routine test
